PIX4605265: Astronaut training in parabolic flight - Astronaut training in zero - G - Astronaut Andre Kuipers is training in weightlessness aboard a Russian plane in the Star City, in preparation for his stay aboard the International Space Station (ISS) in April 2004. ESA astronaut Andre Kuipers, from The Netherlands, enjoys weightlessness inside a Russian aircraft performing a parabolic flight at the Gagarin Training Center, also known as Zviezdny Gorodok (“Star City”), near Moscow, as part of his preparation for the DELTA mission to the International Space Station (ISS) in April 2004. Andre Kuipers was launched into space onboard Soyuz TMA - 4 on April 19 with Russian mission commander Gennady Padalka and NASA astronaut Michael Fincke. The spacecraft successfully docked with the ISS two days later. Andre Kuipers then spent eight and a half days onboard the orbital outpost and carried out an extensive experiment programme in the fields of life sciences including physiology, biology and microbiology. His programme also included some physical science, Earth observation and technology experiments as well as education activities. He returned to Earth on April 30 onboard Soyuz TMA - 3 with the former ISS permanent crew, Russian cosmonaut Aleksandr Kaleri and British - born NASA astronaut Michael Foale, who were replaced by Padalka and Fincke / Bridgeman Images

PIX4625102: Saturn seen by the Cassini probe 04/2007 - Saturn from Cassini spacecraft 04/2007 - Image obtained by the Cassini probe on 13 April 2007 at a distance of 1.8 million km from the planet. Colorful Saturn tilts its darkened ringplane towards Cassini. Against the dark sky, the rings are made visible by the light that scatters through them towards the camera. The F ring shepherd moon Pandora (84 kilometers, or 52 miles across) is faintly visible at the top, left of center. Pandora's brightness was increased by a factor of three to aid its visibility. This view looks toward the unilluminated side of the rings from about 18 degrees above the ringplane. The planet is visible through the innermost and outermost portions of the rings. The images were obtained by the Cassini spacecraft wide - angle camera on April 13, 2007, at a distance of approximately 1.8 million kilometers (1.1 million miles) from Saturn / Bridgeman Images

PIX4625173: Saturn seen by the Cassini probe - Saturn seen by Cassini - Saturn seen by the Cassini probe on 22 August 2008 at a distance of 1.2 million km from the planet. The Cassini spacecraft looks toward the sunlit face of Saturn's rings, whose shadows continue to slide southward on the planet toward their temporary disappearance during equinox in August 2009. This view looks toward the sunlit side of the rings from about 3 degrees below the ringplane. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft wide - angle camera on Aug. 22, 2008 at a distance of approximately 1.2 million kilometers (728,000 miles) from Saturn. Image scale is 66 kilometers (41 miles) per pixel / Bridgeman Images

PIX4625336: Titan, Saturn satellite seen by Cassini: Visible and infrared composite image of Titan taken by the Cassini probe on September 12, 2013. View of methane and ethane lakes. - This false-color mosaic, made from infrared data collected by Nasa's Cassini spacecraft, reveals the differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn's largest moon. Titan is the only other place in the solar system that we know has stable liquid on its surface, though its lakes are made of liquid ethane and methane rather than liquid water. While there is one large lake and a few smaller ones near Titan's south pole, almost all of Titan's lakes appear near the moon's north pole - Scientists mapped near-infrared colors onto the visible color spectrum. Red in this image was assigned a wavelength of 5 microns (10 times longer than visible light), green 2.0 microns (four times longer than visible light), and blue 1.3 microns (2.6 times longer than visible light) - The orange areas are thought to be evaporite - the Titan equivalent of salt flats on Earth. The evaporated material is thought to be organic chemicals originally from Titan's haze particles that once dissolved in liquid methane. They appear orange in this image against the greenish backdrop of Titan's typical bedrock of water ice - In this mosaic, Kraken Mare, which is Titan's largest sea and covers about the same area as Earth's Caspian Sea and Lake Superior combined, can be seen spreading out with many tendrils on the upper right,. The big dark zone up and left of Kraken is Ligeia Mare, the second largest sea. Below Ligeia, shaped similar to a sports fan's foam finger that points just up from left, is Punga Mare, the third largest Titan Sea. Numerous other smaller lakes dot the area. Titan's north pole is located in the geographic location just above the end of the “” finger”” of Punga Mare. The data shown here were obtained by Cassini's visual and infrared mapping spectrometer during / Bridgeman Images

PIX4625563: Mimas, satellite of Saturn, seen by the Cassini probe on 13/02/2010 - Saturn's moon Mimas seen by Cassini spacecraft - February 13 2010 - The Mimas satellite seen in false colours by the Cassini probe on 13 February 2010 has a distance of 16,000 km from the satellite. Color differences reveal differences in terrain nature. Mimas is about 400 km in diameter. At the right centre is the large impact crater Herschel, 130 km wide. Subtle color differences on Saturn's moon Mimas are apparent in this false - color view of Herschel Crater captured by Nasa's Cassini spacecraft during its closest - ever flyby of that moon. The image shows terrain - dependent color variations, particularly the contrast between the bluish materials in and around Herschel Crater (130 kilometers, or 80 miles, wide) and the greenish cast on older, more heavily cratered terrain elsewhere. The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition between the two terrains. Herschel Crater covers most of the bottom of this image. To create this false - color view, ultraviolet, green and infrared images were combined into a single picture that exaggerates the color differences of terrain on the moon. These data were combined with a high - resolution image taken in visible light to provide the high - resolution information from the clear - filter image and the color information from the ultraviolet, green and infrared filter images. The natural color of Mimas visible to the human eye may be a uniform gray or yellow color, but this mosaic has been contrast - enhanced and shows differences at other wavelengths of light. During its closest - ever flyby on Feb. 13, 2010, Cassini came within about 9,500 kilometers (5,900 miles) of Mimas. This view looks toward the northern part of the hemisphere of Mimas that leads in the moon's orbit around Saturn. Mimas is 396 kilometers (246 miles) across. North on Mimas is up / Bridgeman Images

PIX4626096: Oil Lake on Titan - Titan's ethane ocean - Artist's view of a hydrocarbon lake (methane - ethane) on the surface of Titan. Compared to the Earth, Titan is very far from the Sun's warming rays - - about ten times further - - and this leaves Titan a very cold world. Titan has an average surface temperature of minus 290o F. If there is any water on Titan it is frozen hard as steel, yet Titan may be the only body in the Solar System besides the Earth that harbors a liquid ocean. Titan's ocean would not be one of water, rather it would probably be composed of (very cold) liquid ethane. (On the Earth we know ethane as a colorless, odorless, nontoxic, flammable gas, a constituent of natural gas and petroleum.) If this werenn't exotic enough, immediately beneath this ocean may lie hundreds of feet of frozen acetylene (a common component of welder's torches) / Bridgeman Images

PIX4626110: Oil Marsh on Titan - Ethane swamp on Titan - Artist's view of an ethane marsh on the surface of Titan. Initially astronomers thought that Titan's entire surface may be covered by a liquid hydrocarbon ocean. More recent observations in infrared wavelengths suggest otherwise. In this image the artist is suggesting that Titan may be host to extremely cold ethane - methane swamps / Bridgeman Images

PIX4626117: Titan Exploration - Illustration - Exploring a hydrocarbon swamp on Titan - Automatic balloons fly over an oil marsh on the surface of Titan. A pair of balloon - borne probes leisurely survey a methane - ethane “” swamp”” on Titan. Each probe carries its own spot light illuminating the terrain below, augmenting the haze - filtered sunlight. Scientists have long speculated that methane and ethane may exist as liquids on Titan's extremely cold surface, but it wasn't until 2005 that the Cassini spacecraft's radar imager detected what indeed may be large hydrocarbon lakes on Titan's northern latitudes. While it is believed that the liquid in these lakes would be primarily methane and ethane, this won't be confirmed until the lakes - - if that's indeed what they are - - are actually sampled. Whatever lies on Titan's surface, there is the possibility that the ancient and exotic environment has given rise to compounds heretofore unknown on Earth. Large quantities of Methane and ethane exist in Earth's relatively warm environment as components of natural gas / Bridgeman Images

PIX4629411: Kepler's Law - Illustration - The segment that connects the planet to the Sun sweeps equal areas in equal times. In other words, the speed of a planet becomes greater when the planet approaches the Sun. It is maximum in the vicinity of the shortest radius (perihelie), and minimal in the vicinity of the largest radius (aphelie). Second Kepler's law, the line joining a planet and the Sun sweeps out equal areas during equal intervals of time. The planet moves faster near the Sun, so the same area is swept out in a given time as at larger distances, where the planet moves more slowl / Bridgeman Images
